Connecticut to Install Third Digester for Biofuel


AG-Grind Energy will install a digester with a capacity of 850,000 gallons to convert food waste and animal manure into biofuel to be converted to electricity with an output of 450 kW. The installation will be funded in part by a grant from the Natural Resource Conservation Service and an investment tax credit partner.

The project will be erected at a cost of $5 million and will sell electricity to farms and municipalities. Two other digesters operate in Connecticut, located in Southington and East Canaan respectively.

As with many projects to convert waste to biofuel, obtaining a satisfactory volume of substrate is critical to maintain throughput. The project will cooperate with Blue East Compost in Hartford to collect food waste. U.S. Senator Richard Blumenthal attended the ceremony announcing the project and he has inserted a provision for recycling food waste in the 2018 Farm Bill.
